SWlTGH-WIOVEIVENT FOR STREET-RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 426,306, dated April 22, 1890.

Application filed July 30, 1889. Serial No. 319,220. (No model.)

T all whom, it muy concern:

Be it known that I, HENRY L. NODLER, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Switch-Movements for Street-Railways; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the iigures of reference marked thereon, which form a part of this specification.

This invention relates to an improved Inode of operating street-railway switches; and it consists of a stationary device operated from the Streetcar, by which, in conjunction with other devices connected to the switch, the saine is manipulated.

The object of this invention is to provide means whereby the switch may be worked easily, quickly, and surely without slowing u p the car and without the danger of missing or overrunning, as all working parts work within fixed and previously-arranged limits. I attain these objects in the accompanying drawings, in which- Figure 1 is a top view of a switch and adjacent portions of track, showing, also, in dotted lines part of street-car above. Fig. 2 is a side view or vertical elevation of the part illustrated before, showing parts of the street-car in full lines. Fig. 3 is a longitudinal vertical section on lino 3 3 of Fig. 1. Fig. 4 is a vertical eross-section on line -.t 4t of Fig. 1. Fig. 5 is a perspective view of the shifting-frame 10.

7 is the switch-plate, and 8 the switch.

9 are portions of the track.

10 is a shifting-frame pivoted at 11, and loosely connected with switch 8 by means of a pin 12.

13 is another plate below frame 10, having two vertical flanges 14 14, and is rigidly secured to the switclrplate or to mties below. Part 15 of frame 10 moves in a groove cutout of the bottom of the track in the switch-plate, so as to bring it below the action of the wheels, as shown at 1G, Figs. 1 and 3. Part 17 of frame 10 may be entirely below the track, as shown at 18, Figs. 1 and Frame 10 might be pivotcd to the switch-plate, but more prefera-bly it is pivoted to plate 13.

19 is a roller journalcd onto a vertical shank 20, and is ordinarily kept up by a spring 21. The upper end of this shank 2O may be provided with a treadle 22 if to be operated accordingly, or if-to be manipulated by hand a suitable lever-connection 23, as indicated by dotted lines, maybe provided. There cars always make turns in only one direction, one roller is sufiicient. Otherwise one or two must be put on each side, as the particular case may require it.

The operation is as follows: The car approaching the switch, roller 19 is pressed, either by foot or hand,whatever way is used, down, so it may enter between one of the iianges 1l and the adjacent part 2l of frame 10, at which moment the parts are in a position as shown at 25, Fig. 1. At 26 in Fig. 1 and in Fig. @t the roller has entered between .parts 11 and 2l and the switch is' about set. Having passed over the switch, the operator releases his hold on the upper connection of roller 19 and the same is returned to its normal vposition by spring 21. In place of the roller 19, a solid wedge-shaped cam might be used; but I prefer the former, as it causes less friction. Upright anges 14 and plate 13 are not absolutely needed as far as operating the device is concerned. Their main object is to protect the exposed parts of frame 10 and to guide roller 19 properly against part 21 of frame 10.

In the present case the parts attached to the car are inside of the platform. They could, however, be located outside, if preferred.

Having described my invention, I claim as I TOO on its forward end, and havin gnpright lan ges 24 connected with each other by the front and rear parts l5 and 17 of said frame passing underneath the track, the device whereby the switch is thrown, and which device is attached to the car and capable of being brought in contact with either one of said anges, whereby the fra1ne,with the forward end of the switch, is moved to either side, all as shown and described.

3. In a switch-movement, the combination, with the switch proper having its forward end pivotally connected to the rear end of a frame l0, the opposite and forward end 'of which frame is also pivoted below the railW and adjacent to the switch, said frame having vertical anges 24 rising on each side of the switch and of those portions of the rail on which it rests, of stationary vertical ilanges 14 outside of the movable flanges 24, whereby these latter are protected from injuries, and also form with thexn a channel diverging toward the shifting device descending from the approaching car, insuring a gradual and proper contact necessary for throwing the switch, all as shown and explained.

In testimony whereof I affix my signature in presence of two witnesses.
